Improving Energy Efficiency in Pharmaceutical Manufacturing Operations -- Part II: HVAC, Boilers and Cogeneration

Whereas Part I of this article ("Improving Energy Efficiency in Pharmaceutical Manufacturing Operations ? Part I: Motors, Drives and Compressed Air Systems", Pharmaceutical Manufacturing, Feb. 2006) focused on motors, drives and compressed air systems, Part II will review, briefly, potential improvements in heating, ventilation and air conditioning (HVAC) systems, overall building management and boilers. Research in this article was first published last September, in an extensive report developed by the Energy Analysis Department at Lawrence Berkeley National Laboratories for the Environmental Protection Agency?s Energy Star Pharmaceutical Focus. The 90-page guide, ?Energy Efficiency Improvement and Cost Saving Opportunities for the Pharmaceutical Industry,? is available in pdf format at www.energystar.gov. The U.S. pharmaceutical industry spent nearly $900 million on energy in 2002. As energy costs increase, more companies are looking into energy efficiency measures Considered individually, each measure may offer small savings, but combined they add up to significant savings and short payback periods
